At Company X senior sales representatives visit the home office once every 30 days, and junior sales representatives visit the home office once every 20 days. The number of visits that a junior sales representative makes in a 2-year period is approximately what percent greater than the number of visits that a senior representative makes in the same period?

HiCan anyone help me with the other version of the question where the answer will be 33%. I was trapped.But i am confused in the wording of the question.I suppose we are asked to calculate the change between each...

If the question were: "The number of visits that a senior sales representative makes in a 2-year period is approximately what percent smaller than the number of visits that a junior representative makes in the same period?", then the answer would 33%: (36-24)/36=1/3=~33%.

When asked "a is what percent greater/smaller than b" always put b in the denominator: (a-b)/b*100.

for a 2 year period ( senior) 2/30 >> \(\frac{1}{15}\)for a 2 year period ( Junior) 2/20 >> \(\frac{1}{10}\)

To find Junior - senior / senior * 100

{1/10} - {1/15}/ {1/15} * 100

= 50 percent

Responding to a pm:

When you say Senior is 1/30, what do you mean by it? It is the rate of visit. The time of visit is 30 days. The rate is 1/30. Similarly, the rate of visit for junior is 1/20.The 2 yrs has no significance in this case. The rate stays the same for every time interval.

Hope it helps.

I got the answer to this question correct, but the above has confused me a bit.

In the question, I treated Junior as A and Senior as B, therefore (A-B)/B = (36-24)/24 = 50%.

But in the above you say that if it were the percent that senior was smaller than junior, it would be (36-24)/36 as "When asked "a is what percent greater/smaller than b" always put b in the denominator: (a-b)/b*100".

{1/20} - {1/30}/ {1/30} * 100 = 50%

YOu're the best Karishma!!

I performed a lengthy calculation, though not really performed the multiples and divisions but left the big numbers there for cancelations, and also realized that the number of year (1 year or 2 or whatever) does not mean anything. The rate is the same, so this question is as simple as:
